We are not cutting corner in this grinding process time to increase the production. The OD makes contact with the bore on the tool holder and along with the internal bore tolerance it’s critical to be able to maintain the overall runout after a long period of usage. SUJ2 alloy steel from Japan Made from SUJ2 alloy steel from Japan which is equivalent to AISI 52100 and hardened to HRC 46-48 Mirror Finished The 2 taper surfaces are precision ground in a CNC grinder Shigiya from Japan to roughness tolerance of Ra 0.4 Taper Accuracy An ER collet is selected during the CNC grinding process to check the 2 taper contact surface's accuracy Robotic Automation in Manufacturing We optimize our manufacturing workflow for both efficiency and accuracy by utilizing robotic arms to load and unload ER collet stock into the Shigiya CNC grinders which are made in Japan. Combining the robotic arms with a reliable CNC grinder is our formular to control tight tolerance in a mass production environment. 5 Micron Runout Each collet is inspected 3 times at 0, 120, and 240 degree at 4 times diameter to guarantee the 5 micron (0.000197") runout tolerance. This inspection process is also repeated 3 times with fully disassemble collet from the collet nut and the tool holder to guarantee consistent runout tolerance Made in TAIWAN Conform to DIN6499B We have more collects available at My Ebay Store: All Available to Ship NOW! at Fixed Prices SHIPPING: UPS Ground Buyer pays ACTUAL UPS shipping & insurance, and a $3.00 handling fee for this item to be shipped to all states within the continental United States.
